, .To all whom it may concern:

Be: it known that I, ROBERT P; Soon, I a citizen of the United States,' residing at 'Cadiz, Harrison county, Ohio, have invented E5 certain ,new and useful Im rovements in 'j :Gi eemPea-Vine-Hulling Mac ines,of which the following is a'speeification.

My invention'relates to green iea vine f" hulling machines. and one of the 0 jects of myinvention is to improvetheconstruction Q or such-machines shown'in'Letters Patent ""j'Nunih'er's 499,397 June 13, 1893 toR. Scott; 957,442 May 10, 1910,;to R. P. Scott; 1 957,443 May 10,1910 to R. P. Scott; 957,444 .5 May 10, 1910 to T. A. Scott; 500,299 June 11 227, 1893 to Scott and Chisholm.

One of the objects of my invention is to improve the-construction of the' beaters in 1 11 achines andalso the construction and 2, arrangement of the lifting} ribs,-. theribs' .biiigprovided with guards so as to increase thqefliciency of themachine, and its capacity to hull-and separate peas.

Ihgeneral my 'new pea hailing machine f jil'resehibles those indicated inthe' patents re;

ferred" to and retains intact the .well esl'ltablished impact process, Certain faults litiye been discovered in the use of these ma-' c.hiii'es since theinvention of the Chisholms and offthisapplieant, especially. .with rela} Ition tothe re t 'flrements-in canned goods, in .'which anmch" igher grade and more ole-e, ;tion in packing are now demanded.- Broken .'peas,w-hieh disintegrate'and impair ,the genleral 'ap'pearanceof the goods are particug larly to be. avoided. Inorder to partially overcome these difficulties, many. packers ,have adopted whatrare termed. tandems i siicccssively through; two machines. Others enough" a achine once, if properlyadasted, and regulated in accordanceiwith my est impact in hulling are more liable to injury by being struck after they are out of the pod. It will be seen that my improved lifting ribs greatly facilitate the sitting of .-.namely machinesin which the "vines are run;

an the wines: through the :same machine twice. The expense and. delay of these ere I that allpe s'can 'be-liulled by running-them' invention; The peas which require the mildi the h ulled peas, so that when the vines and peas are struck, many of the hulled peas will be'thrown through the inner guard upon the lifting ribs or against the solid portions of the perforated rubber screen forming the wall of the drum, whereupon they roll down between the guard and the rubberscrecn and thereafter pass the outer edge of the lifting rib. These peas may t-llllS' be discharged upon the perforated rubber screen below and will not roll inwardly off the rib,

and drop upon a mass of vines or into the path of the impact heaters, and he again struck with consequent injury to the peas.

. The prior machines while perfect in general principle have been too rigid in detail to suit; the present exacting requirements of the trade. I find thatby making the beaters of springy material, such as sheet metal, the blow given thereby to the peas is elastic and yielding to some extent, with a consequent reduction in the number of broken peas. varying the pitch afigle and height of the heaters, the'machinegfis adapted for .workon different kinds of poas'so as to mostcfi'ectively hull them. 1 I I By SlftJ-llg out .the peas, instead of delivering them with the wasteyines, a considerable economy, is eifected since the cost of peas is .now much more than formerly and there is particularly a demand for a more tender and perfect product. Peas are not allowed to mature as formerly and theexpenseof labor and handling has been increased. Owing to the delicate nature of the peas, it is desirable not to retain them among the vines, long enough'to reach the discharge end of the machine. In order to attain the above objects,

the improved lifting rib, the guard therefor,

,the springy heaters and theiradjustment as to pitch and height, all act in combination to .quickly and eii'ectively hull the tender eas.

p With the above objects in viewniy invention consists iir the parts, improvements and 'eombinations more fully pointed gut hereinafterf -Referring now'. to the drawings: Figure 1 shows agfro'nt elevation of outer elevating cylinder and innerbeater carrying drum. Fig. .2 shows a detailed view of ny improved lifting rib. Fig. 3 shows an edge view of another lifting rib or modification. Fig. 4 shows an end view of Fig. 3. Fig.

5 shows a plan view of a lifting rib cut away connected by elevating ribs An inner drum shaft.

with a central shaft carries the heaters. The feed ends of both drums, the lifting ribs and heaters are shown in Fig. 1. The six sides of the outer drum are covered vby scr'eens which may be of sheet metal or wire but are preferably of perforated rubber, 1, Fig. 1, held inframes secured to the elevating" ribs 2. The inner beater carrying drum 3 Carries heaters 4 rotated by shaft 5, arranged in sets alon the The rotation of the outer revo uble drum and inner beater carrying drum will be assumed to be clockwise as indicated by or prism integral the numerals 1 to 12".

e5 machine, which if they do, will ransom.

When the vines with peas attached as they come mowed in bulk from the field are fed into the machine they are caught by one of the lifting ribs 2 and carried around and up to about the 11 oclock position indicated by the numeral 11, when they drop'ofi into the path of the more rapidly revolving heaters 4. The heaters striking the vines throw them across to about the two oclook position,'i'ndicated by the numeral 2. The foregoing operation has been common in pea vine ul ing machines but it will be seen that when the vinesare struck and any of the nea'seliberated there has been but one chance of dischar 'ng the 'hulled peas on the two oclock si e of the machine that is if the peas would strike a perforation fairly and be thrown through. Otherwise they wouldstrike the rubber covering between the holes and drop down upon the mass of vines or be. imprisoned between the vines and the 1 1 upper surface of the-lifting rib. That many eas are thus retained inside is indicated y the fact that almost all the hulled are found directly under the seven-o ock osition showing that the principal sifting is done as the peas and vines roll over themselves at that oint; In accordance with my invention, t e hulled peas are given a much better chance'to get to the outside at once as they are struck and thrown across the top. That is to say, if the peas once get away from the vines I do not give them a-chance to get mixed up again. To do this I first put a ledge 7' along ,the'inner side-of the main rib-2 to from rolling ofi toward-t e center of the revent any peas I mass of vines lying down on the next rib.

In accordance with my invention, the liulled peas roll upon a sifting surface which may be the perforated rubber screen forming the outside of the drum. The vines are kept from coming into contact with the rib so as not to become mixed with the hulled accomplishing this result may be varied. 'As shown in Fig. 3, I may make use'of a metal sheet 60 raised atintervals 61, upon peas dropping down between, and rolling across the rib. after passing the three screen 6 extending from an auxiliaryledge 7 mounted upon the main rib 2. The ledge 7 prevents the peas rolling inwardly toward the beater carrying drum, which would hapthe three ocloci: position, in which case the peas would drop into the path of the beaters-and he struck again or would drop down upon the top of a mass of vines lying against a rib below. The wire net 6 may run about aha-1i or third way along the rubber screen more or less. A

Another feature of my invention consists in the manner of taking care of the peas whenthey'roli to the outer edge of the lifting rib. This rib does not run out against the frame 19 of the rubber covering as heretofore, but oniy at places or intervals 20 to support the frames 19. The rib-is cut away or spaced at 21 so that the peas can roll down ast the outer edge, of the rib, and through to and u on the clear surface of the screen below. tis important to notime that the peas cannot get an the rib until the rib has passed the three oclock position. The screen upon which the one tien roll is in the best position for si ting purposes that is to say, it lies at an. angle of some forty-five degrees with no vines in the way. One reason for having a very open wire net 6 to catch the vines is less dan r of hulled peasstriking a wire. Some In pods which have'been detached from the vines get through the wire net but are arrested .by the rubber screen. These pods will drop back through the wire when at the top or roll 'out from between the wire and rubber at the nine oclock position. One advantage of my wire net instead of a more rigid device is its adiustability because of its pliability. There aretwo ways ofthrowing as they areraised up from the bottom of the outer cylinder, namely by narrowing the'rib so the vines would drop-or roll oif quicker or by changing the. slant of the rib. N ow it 'will be seen that I cginot only ad ust the Laten c he win net pen before the main lifting rib 2 reachedthe vines out upon the heaters earlier .or later along thenb but I either to be struck again or to fall upon a peas which reach the rib. The means for the tops of which the vines would fall, the

oclock position o the vines may be kept free from the hulled peas, by means of a wire that there will be I can also adjust or change it for a part way and let the rest be difierenuthat 18 to say,

- I can make the net of such slant at one place that the vineswill drop off and be struck once and at another. place cause the vines to drop off earlier and be-struck twice. By

thi's'means I can arrange the front part of the machine .or-fced end tostrike the vines but once and'later at the discharge end to strike them twice. This adjustability is quite an advantage since'some' varieties of peas are much more tender and at the same time'niore diiiicult to hull. By means of this adjustable feature .I can treat the peas more lenientlyat first and at the same time so severely at the tail'end'of the machine that no peas will escape without being hulled.

' reason of dilierent varieties of peas but the of sprin whole hulling system differs m different years. A wet or dry'season changes the conditions and the'prevailing weather is apt to alter everything. y

One object of the invention is to provide a beater Figs. '6 and 7 ,with a certain amount to it so asto be less hard on the furthermore to make the same adpeas an ejustablein their pitch. This regulates the speed with which the vines'and peas pass justed in its slant. This controls the spiral.

steel beater shown herein.

from the feed to the discharge end of the machine. This feature of, my invention consists in making the beater of spring steel or. of any flexible nature; The beaterv has a portionv turned over to form a foot 22 or resti'ng'su'rface which is provided with elongated holes 23 so arranged that by simply loosening the bolts 24 the beater can be ador forward thrust against the vines feeding through the machine. In former machines heavy rigid heaters were used which made a dead stroke. I have discovered that a spring stroke such as given by'a piece ofthin' steel or a light pine shingle, opens the pods more readily and for this reason'I use the spring Furthermore I have found'that different peas in different seasons require aless rapid stroke and more of them. Hence with my ;new beater. the speed can be slowed down andlat the same time the beater put straightener more'parallel with the central shaft through the drum so asa hold the vines in the machine longer.- Another adjustment I useis to increase-the height of the-beater or rather increase 4 its Y radial length from, the center of the shaft or drumiwhich carries thc'beaters. This isac- I 'complished by bolts 25 and slots 26 which adjust the ends 27 of the beater. It will be seenby this last arrangement-the heaters can be set not so far out at the beginning or feed end and then farther out nearer the exit end. By this means the peas receive a harder or more rapid stroke toward the last and'thus if any podsare of very tough or re;

sisting'nature, they will be opened before they get clear of the machine and thatwithout an equally severe treatment at the-start.

Asthe heaters must not come too close to.

the lifting ribs and if it is desired to extend them to a greater height radially the lifting rib'may be made of varying width. In .the form cfthe invention illustrated, the ribis cut away at 28 as shown in Fig. 5, so as to receive the beater of greatest height without decreasing the clearance bet-ween said beaters and 'the adjacent portion of the lifting rib. -Moreover the narrow portion of the lifting-rib will begin to let the peas-drop: earlier in the revolution, that is to say at about seven or eight oclockposition, u on or into the path of the heaters There ore when struck they are thrown to the eleven or twelve oclock position. They then drop .again and are .struck thus making adouble :stroke in each round of the lifting ribs thereby making a further certainty of all the peasbeing'hulled before passing out of the machine, but not faster than the siftingaction is taken care of.

l have found it quite important-that the machines are adjustable in several ways to accommodate different conditions and since thepea season is very short alladjustments must be made quickly; I

It will'be seen that by changing the slant of the net or screen 6 T avoid making the rib 2 adjustable in width which would accomplish the same purpose.

The operation of myimproved machine will be apparent from .the above description.
